Numerical value inputting device and electronic equipment

Abstract

A numerical value inputting device includes a touch panel and a digit number changing part. The touch panel includes a display face to display a numerical value display area and detects simultaneously two pressed positions onto the display face. The digit number changing part changes the number of digits of a numerical value displayed on the numerical value display area in accordance with separation or approach of the two pressed positions.

What is claimed is: 
     
       1. A numerical value inputting device, comprising:
 a touch panel including a display face to display a numerical value display area and detecting simultaneously two pressed positions onto the display face; and 
 a digit number changing part changing the number of digits of a numerical value displayed on the numerical value display area in accordance with separation or approach of the two pressed positions, 
 wherein, the digit number changing part, in a case where the two pressed positions are overlapped with displayed position of the numerical value displayed on the numerical value display area, increases the number of digits of the numerical value by interposing a predetermined numeric character between the two pressed positions, when the two pressed positions are separated along an arranging direction of the numeric characters of the numerical value, and decreases the number of digits of the numerical value by deleting a numeric character between the two pressed positions, when the two pressed positions are approached along the arranging direction of the numeric characters. 
 
     
     
       2. The numerical value inputting device according to  claim 1 , further comprising:
 a numerical value changing part changing a value of a numeric character in accordance with press of the numeric character constituting the numerical value displayed on the numerical value display area. 
 
     
     
       3. The numerical value inputting device according to  claim 2 , wherein
 the numerical value changing part, in a case where at least one of the two pressed positions is overlapped with the numeric character constituting the numerical value displayed on the numerical value display area, increases the value of the numeric character, when the two pressed positions are separated along an orthogonal direction to the arranging direction of the numeric characters, and decreases the value of the numeric character, when the two pressed positions are approached along the orthogonal direction to the arranging direction of the numeric characters. 
 
     
     
       4. The numerical value inputting device according to  claim 2 , wherein
 the numerical value changing part increases or decreases the value of the decided digit, whenever the press of the numeric character decided by the two pressed positions on the numerical value display area is continued for a predetermined time. 
 
     
     
       5. The numerical value inputting device according to  claim 2 , wherein
 the numerical value changing part circulates and increases or decreases the value of the numeric character decided by the two pressed positions on the numerical value display area. 
 
     
     
       6. Electronic equipment comprising:
 a numerical value inputting device, 
 wherein the numerical value inputting device includes: 
 a touch panel including a display face to display a numerical value display area and detecting simultaneously two pressed positions onto the display face; and 
 a digit number changing part changing the number of digits of a numerical value displayed on the numerical value display area in accordance with separation or approach of the two pressed positions, 
 wherein, the digit number changing part, in a case where the two pressed positions are overlapped with displayed position of the numerical value displayed on the numerical value display area, increases the number of digits of the numerical value by interposing a predetermined numeric character between the two pressed positions, when the two pressed positions are separated along an arranging direction of the numeric characters of the numerical value, and decreases the number of digits of the numerical value by deleting a numeric character between the two pressed positions, when the two pressed positions are approached along the arranging direction of the numeric character. 
 
     
     
       7. The electronic equipment according to  claim 6 , wherein
 the numerical value inputting device further includes: 
 a numerical value changing part changing a value of a numeric character in accordance with press of the numeric character constituting the numerical value displayed on the numerical value display area. 
 
     
     
       8. The electronic equipment according to  claim 7 , wherein
 the numerical value changing part, in a case where at least one of the two pressed positions is overlapped with the numeric character constituting the numerical value displayed on the numerical value display area, increases the value of the numeric character, when the two pressed positions are separated along an orthogonal direction to the arranging direction of the numeric characters, and decreases the value of the numeric character, when the two pressed positions are approached along the orthogonal direction to the arranging direction of the numeric characters. 
 
     
     
       9. The electronic equipment according to  claim 7 , wherein
 the numerical value changing part increases or decreases the value of the decided digit, whenever the press of the numeric character decided by the two pressed positions on the numerical value display area is continued for a predetermined time. 
 
     
     
       10. The electronic equipment according to  claim 7 , wherein
 the numerical value changing part circulates and increases or decreases the value of the numeric character decided by the two pressed positions on the numerical value display area. 
 
     
     
       11. The numerical value inputting device according to  claim 1 , wherein
 the digit number changing part, when the two pressed positions are separated along the arranging direction of the numeric characters and a distance between the two pressed positions exceeds a predetermined threshold, interposes the numeric character of 0 between the two pressed position to increase the number of digits of the numerical value, and then, when the two pressed positions are further moved without releasing the press to expand the distance, increases the value of the numeric character of the interposed digit in accordance with an increasing amount of the distance between the two pressed positions. 
 
     
     
       12. The electronic equipment according to  claim 6 , wherein
 the digit number changing part, when the two pressed positions are separated along the arranging direction of the numeric characters and a distance between the two pressed positions exceeds a predetermined threshold, interposes the numeric character of 0 between the two pressed position to increase the number of digits of the numerical value, and then, when the two pressed positions are further moved without releasing the press to expand the distance, increases the value of the numeric character of the interposed digit in accordance with an increasing amount of the distance between the two pressed positions.
